My personal hygiene is stellar (perhaps a little over enthusiastic.) I shower and brush my teeth at least twice a day. I also use mouth wash and floss.

My personal appearance is something else though. I just don't bother. As long as my fat bits are covered up I am relatively uninterested in the rest. There is nothing that is going to make me pretty so I see no point in trying.

I also prefer to avoid mirrors so anything that will involve too much time in front of one is out.

Personally no matter how bad I may get I will never not shower. It just makes me uncomfortable and would only make me feel worse. I understand the lack of motivation to not do so though.

At the very least a hot shower/bath can be calming. (Or a safe place to cry without anyone noticing.)
